Description

Breakwater structure of deep water {The structure of breakwater in deep sea}

The present invention relates to the structure of a breakwater, which is a facility that is designed to maintain the quietness of the harbor and to ensure the safety of ships anchored in the harbor and to protect all the facilities of the harbor from blue waves. Various structural types of breakwaters are selected according to the basal topography of the sea floor, the strength of the waves, and the depth of the water. The different types of structural types of these breakwaters include upright breakwaters, hybrid breakwaters, and stone slopes. The most suitable breakwater system will be selected and installed.

The breakwater (1) is an upright breakwater or hybrid breakwater or a sandstone incliner as described above, and forms a foundation part (3) from the bottom of the sea to a certain depth from the bottom of the sea and forms an upper structure on top of the foundation part (3). In this case, the foundation part is formed by stacking natural stone stones. As shown in FIG. 1, in the case of a hybrid breakwater, the slope of the body is generally formed in a gradient of about 1: 2. In this case, when the height of the body is 30M, the base mound width of the base is about 111M. Therefore, a huge amount of sandstone is required. The caisson 4 as shown in FIG. Although the structure of the upright breakwater using been proposed, this also when the height 30M cheil computationally base unit bottom width of the mound is a situation that the structure of the breakwater member is further riprap is significantly less than the required long, approximately 74M is required.

The present invention devised to build a rugged breakwater while significantly reducing the use of precious stone, a precious natural resource bar, as described in detail with reference to Figure 3 attached to this, but especially in the case of deep water use significantly The body of the breakwater (1) implemented according to the present invention, characterized in that it can be reduced as an upright breakwater using a kind of caisson (4) with a constant width (W) and height (h) on the upper surface of the sea bottom (10) The base end 12 is formed of a slope 11 with an inclined plane slope of 1: 1.5, and is spaced at a predetermined distance from the inner sea side and the outer sea side of the upper surface of the base end 12 at a constant height so that the space 13 is provided. The hollow block 14, which is a hollow portion 14a having a hollow portion 13a inside and is formed of a quadrilateral box of a constant size, is stacked in multiple stages so that the hollow block 14 layer laminated on the inner sea side and the outer sea side is a vertical wall B on the inner sea side. To the vertical wall (Ba) The space between the inner hollow portion 13a of the hollow block 14 constituting the inner sea vertical wall B and the outer sea vertical wall Ba and the inner sea vertical wall B and the outer sea vertical wall Ba The section 13 is filled with a seating stone 11 up to the upper end of the wall (B), (Ba) and has a constant width and height on the upper end face of the face of the seating stone (11) and a vertical partition wall (16) on the inner middle part. A deep water breakwater structure is constructed according to the present invention by placing the caisson 15 and filling the sandstone 11 in the inner space of the caisson 15 and placing the cap concrete 17 on the upper surface of the caisson 15. .

As described above, an upright breakwater constructed at a deep water position implemented according to the present invention uses the hollow block 14 as the basic body of the breakwater 1 to minimize the width of the body and further stack the hollow block 14. By stacking the inner sea side vertical wall (B) and the outer sea side vertical wall (Ba) to reduce the width of the body to the extent allowed by the safety factor in the structural design, and by placing the caisson (15) on the upper surface of the narrow space secured By selectively filling (B) (Ba) only with the sandstone (11), it can reduce the width of the foundation (12) enough to support the body, thus providing a firm breakwater while drastically reducing the amount of sandstone used. The stacking height of the hollow block and the width of the breakwater body can be arbitrarily adjusted within the design allowable range, so it is very advantageous as a breakwater to be built in a deep water position.

Claims (1)

In constructing an upright breakwater (1) having a minimum width by using a hollow block and a caisson, the foundation end 12 is formed by the sandstone 11 with a constant width (W) and height (h) on the upper surface of the sea bottom (10). It is formed to have an inclined slope of approximately 1: 1.5 and is spaced at a constant distance from the inner sea side and the outer sea side of the upper surface of the base end 12 at a constant height so that the space portion 13 is provided, and has a constant size inside the hollow portion 13a. The hollow blocks 14, each of which is a rectangular box body, are stacked in a plurality of stages so that the hollow block 14 layers stacked on the inner and outer sea sides become the inner sea vertical wall B and the outer sea vertical wall Ba. Space between the inner hollow portion 13a of the hollow block 14 constituting the inner sea vertical wall B and the outer sea vertical wall Ba and the inner sea vertical wall B and the outer sea vertical wall Ba Filling section 13 to the top of the top of the wall (B), (Ba) to the top end, and has a constant width and height on the top of the top of the face of the sand (11) The deep water depth of the caisson 15 having a vertical bulkhead 16 in the figure is filled in, and the inside of the caisson 15 is filled with the sandstone 11 and the cap concrete 17 is placed on the upper surface of the caisson 15.
